Usually this error indicates undefined symbol/reference in the OOT's shared
object (.so) file. To find our the exact problem go to your OOT's build
directory, execute `ldd -r lib/*.so` and provide the full output.
Also to improve the error handling in python/__init__.py change ImportError to
ModuleNotFoundError. Then rebuild, reinstall and run you flowgraph.
